Show HN: Colors – A data-driven collection of beautiful color palettes

I don’t know if your data model (or general hypothesis) is working. There are some truly garish color combinations (too many to be a fluke) on the site, so I’m thinking some colors work better as part of a work rather than as a stand-alone palette

Yes, some are pretty funky :). Gradients, photographs etc can be one reason. Still I think some are pretty nice :).

I don't know how you're doing the palette extraction right now, but if want something to experiment with I'd suggest you take a look at using k-means clustering. In other words see the set of pixels as points in a 3D space (where the axes are red, green and blue) and then perform k-means clustering on the points. You could then extract the palette from the centroids. If k-means doesn't give satisfactory results, try spectral clustering.

Sounds cool, thanks :)! I'll look into some more methods soon!

As a research result, this is still an interesting outcome. Nobody has done this before, to my knowledge.

German tricolour flags are prominent here (current and German Empire). I think that's an interesting result. There may be more national flags, I was looking for something similar to the Spanish flag, but my knowledge isn't that great there.

What do you mean by "data-driven"? What algorithm are you using to produce the palettes?

Hi! It's data-driven in the sense that colors are not picked by hand but rather extracted from curated designs on Pixels (klart.co/pixels) :).

Nice! Though it seems a lot like http://coolors.co, any differentiating aspects?

Coolors looks nice :). I generate all palettes automatically from my design curation Pixels (klart.co/pixels). I want it to be really simple to find color inspiration so you can just go to the site and press space to shuffle until you find something you like :).

I like Pixels very much, thank you for curating this.

Thanks :D

Big fan of coolers.co, really useful tool.

Is there a way to pattern match against a set of requirements, like relative contrast or color difference?

Not yet. Might be something I'll implement. Thanks :)!

Love Colors and Color Science? Come support a dedicated Color Science community StackExchange Q&A site: https://area51.stackexchange.com/proposals/110687/color-scie...

That's way too specific.

Agreed. Why isn't a "color science" tag on the graphic design Q&A site enough?

No. This is a very different audience wanting to do things with colour, e.g. maths. The graphic design site does not have the right moderators and audience for it.

I do interesting things with colour from time to time and find myself in the realms of no documentation and no sensible answers from Stack Overflow. I don't care what code an algorithm is in, or if it was written by Ancient Greeks, what I want is a community that knows stuff about colour spaces, identifying colours in complex images, making palettes from data and so on. The 'graphic design' community isn't about that, for starters there is an expectation to be using applications rather than code for working with images.
